Detailed explanation-1: -Proxy data can provide insights on a range of climate-relevant changes. These include sudden events – such as volcanic eruptions or floods – and gradual, long-term trends – such as warming and cooling, drought, changing sea levels, cyclone patterns, monsoon seasons, fluctuating atmospheric CO2 or thinning ice sheets.
Detailed explanation-2: -These layers contain dust, air bubbles, or isotopes of oxygen, differing from year to year based on the surrounding environment, that can be used to interpret the past climate of an area. Ice cores can tell scientists about temperature, precipitation, atmospheric composition, volcanic activity, and even wind patterns.
Detailed explanation-3: -Borehole temperatures are used as temperature proxies.
Detailed explanation-4: -Ice cores provide direct information about how greenhouse gas concentrations have changed in the past, and they also provide direct evidence that the climate can change abruptly under some circumstances.
